Everything you need to know about Francis Turbine
-
In this article, we are going to introduce Francis Turbine. Francis Turbine is a type of water turbine developed by James B. Francis in Lowell, Massachusetts. It is an inward flow reaction turbine that combines the concepts of radial and axial flow.
In the following, we will review the Francis Turbine Working Principles.The definition of the Francis turbine is a combination of impulse and hybrid turbines. The blades rotate using both the reaction and the impact force of the water passing through them to generate electricity more efficiently. Francis turbines are used to create more electricity in medium or large hydropower plants.
Francis turbine is a type of reaction turbine, a group of turbines in which the working fluid comes to the turbine under very high pressure, and the turbine blades of the fluid work its energy. The liquid is reduced by the fluid due to pressure changes in the turbine blades and is diminished by expressing the degree of reaction, while the rest of the energy is extracted by the turbine volt chamber. Water acts on the characteristics of a spinning cup-shaped runner at the outlet, remaining at low speeds and low rotations with very little kinetic energy or potential. The turbine outlet pipe is designed to help slow down the flow of water and restore pressure.
Francis turbines are the most favored hydraulic turbines. These turbines are the most stable workhorse of hydroelectric power stations. Francis turbine supplies about 60 percent of the global hydropower capacity, mainly because it can work efficiently under a wide range of working conditions. See More In LinquipReference :
